Counts
There may be one this summer on Pelee Island.
Where and When
Dragonflies and damselflies spend most of their lives in or close to water. They live only a few weeks in their adult form and may appear in large numbers around the same time. Males are most visible when they are ready to mate. They are vulnerable (and easy to photograph) when they are mating because they are locked together.
Toolkit
When compared to butterflies, it is much harder to take mobile phone photos. A camera that is good for bird photography will usually work very well.
